    INTRODUCTION

    1.1 Overview

    The High Resistance, 10 kV Decade Substituter (HRRS-10kV Series, Figure 1.1) is a family of instruments that answers the need of the calibration and test community for decades and working stan-dards that go up to 10 T, offering a broad choice of high-range, excellent performance resistance sources. High values of resistance are available for use at high voltages, without sacrificing accuracy, stability, and temperature and power coefficients of resistance.

    The HRRS-10kV Series employs state-of-the-art precision resistors of various types. It is designed specifically for operation at high voltage, with very low leakage to minimize degradation of accuracy.

    The standard models offer a choice of one to nine decades. The panels are clearly labeled showing the step size and maximum allowable applied input for each decade. Custom requirements outside of the standard models can be satisfied.

    The binding posts are insulated with Kel-F high-resistance, non-moisture-absorbing material to ensure low leakage.

    With a resolution as low as 10 and a maximum available resistance of 10 T, the HRRS-10kV Series may be used for exacting precision high-value resis-tance applications that require voltages of up to 10 kV.

    Applications include calibration of meters and meg-ohmmeters, and checking of electrochemical and bio-medical sensors and instruments. These instruments are useful wherever high resistances are required, such as in testing high-impedance amplifiers and the insulation of low-power circuits.

    Observe all safety rules when working with high voltages or line voltages. Connect the (G) terminal to earth ground in order to maintain the case at a safe voltage. Whenever hazardous voltages (> 45 V) are used, take all measures to avoid accidental contact with any live components: a) Use maximum insulation and minimize the use of bare con-

    ductors. b) Remove power when adjusting switches. c) Post warning signs and keep personnel safely away.
